Most of Assyria briefly became part of the Neo-Sumerian Empire

Most of Assyria briefly became part of the Neo-Sumerian Empire (or 3rd dynasty of Ur) founded in c. 2112 BC. Sumerian domination extended as far as the city of Ashur but appears not to have reached Nineveh and the far north of Assyria. One local ruler (shakkanakku) named Zāriqum (who does not appear on any Assyrian king list) is listed as paying tribute to Amar-Sin of Ur. Ashur's rulers appear to have remained largely under Sumerian domination until the mid-21st century BC (c. 2050 BC); the king list names Assyrian rulers for this period and several are known from other references to have also borne the title of shakkanakka or vassal governors for the neo-Sumerians.
